Product Warranty (5 years)
Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for five years from the date of pur-
chase.
This warranty does not apply to any products which have been repaired or altered by
persons other than repair personnel authorized by Advantech, or which have been
subject to misuse, abuse, accident or improper installation. Advantech assumes no
liability under the terms of this warranty as a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous testing, most of
our customers never need to use our repair service. If an Advantech product is defec-
tive, it will be repaired or replaced at no charge during the warranty period. For out of-
warranty repairs, you will be billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For example, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any on screen messages you get when the problem
occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandize
authorization) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a fully-completed Repair and Replacement
Order Card and a photocopy proof of purchase date (such as your sales receipt)
in a shippable container. A product returned without proof of the purchase date
is not eligible for warranty service.
5. Write the RMA number visibly on the outside of the package and ship it prepaid
to your dealer.

CE
This product has passed the CE test for environmental specifications when shielded
cables are used for external wiring. We recommend the use of shielded cables. This
kind of cable is available from Advantech. Please contact your local supplier for
ordering information.
This product has passed the CE test for environmental specifications. Test conditions
for passing included the equipment being operated within an industrial enclosure. In
order to protect the product from being damaged by ESD (Electrostatic Discharge)
and EMI leakage, we strongly recommend the use of CE-compliant industrial enclo-
sure products.
FCC Class A
Note: This equipment has been tested and found to comply with the limits for a Class
A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Opera-
tion of this equipment in a residential area is likely to cause harmful interference in
which case the user will be required to correct the interference at his own expense.

Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
To avoid electrical shock, always disconnect the power from your PC chassis
before you work on it. Don't touch any components on the CPU card or other
cards while the PC is on.
Disconnect power before making any configuration changes. The sudden rush
of power as you connect a jumper or install a card may damage sensitive elec-
tronic components.

EKI-1528-DR Series User Manual 2
1.1 Introduction
The EKI-1528I and EKI-1528CI are network-based serial device servers that connect
RS-232/422/485 serial devices, such as PLC, meters, sensors, and barcode readers,
directly to a TCP/IP network.
Once connected through a EKI-1528 series serial server, devices are able to send
and receive data through a network. This extends the traditional COM ports of a PC,
with access over a TCP/IP network. Through networking, you can control and moni-
tor remote serial devices over either a LAN or WAN. Since the EKI-1528 is connected
through a TCP/IP network, you may need to know some basic facts about networking
in order to connect the server correctly.
The EKI-1528I and EKI-1528CI feature two independent Ethernet ports and MAC
addresses to provide a redundant network mechanism to avoid data loss. The EKI-
1528I and EKI-1528CI provide various operations: COM port redirection mode (Vir-
tual COM Port mode), TCP Server/ Client mode, UDP mode, Control mode and
RFC2217 mode. Detailed descriptions of each operation are provided in a later chap-
ter.

and Web Browser
Supports 32-bit/64-bit Windows 2000/XP/Vista/7/8/8.1, Windows Server 2003/
2008/2012, Windows CE 5.0, and Linux

The DIN rail mount option is the quickest installation option. Additionally, it optimizes
the use of rail space.
The metal DIN rail kit is secured to the rear of the serial device server. The device
can be mounted onto a standard 48.5mm (1.91”) x 66mm (2.6”) height DIN rail. The

devices can be mounted vertically or horizontally. Refer to the following guidelines for
further information.
Installing the DIN-Rail Mounting Kit
1. Insert the top back of the mounting bracket over the DIN rail.
2. Push the bottom of the server towards the DIN rail until it snaps into place.
\
Figure 2.6 Installing the DIN-Rail Mounting Kit
Removing the DIN-Rail Mounting Kit
1. Push the server down to free the bottom of the plate from the DIN rail.
2. Rotate the bottom of the device towards you and away from the DIN rail.
Note! A corrosion-free mounting rail is advisable.
When installing, make sure to allow for enough space to properly install
the cabling.

3. Once the bottom is clear of the DIN rail, lift the device straight up to unhook it
from the DIN rail.
\
Figure 2.7 Removing the DIN-Rail
2.2.1.2 Wall-Mounting
The wall mounting option provides better shock and vibration resistance than the DIN
rail vertical mount.
Before the device can be mounted on a wall, you will need to remove the DIN rail
plate.
1. Rotate the device to the rear side and locate the DIN mounting plate.
2. Remove the screws securing the DIN mounting plate to the rear panel of the
server.
3. Remove the DIN mounting plate. Store the DIN mounting plate and provided
screws for later use.
4. Align the wall mounting plates on the rear side. The screw holes on the device
and the mounting plates must be aligned, see the following illustration.
